I'd get the DNS set on those domains down to a timeout of a minute a week or so before the change. It'll hammer your DNS for a bit, but come the changeover you can change all the mail server IP addresses and then set the time to live right back up again and you shouldn't loose mail. re: actually changing iMail, as someone has already suggested it's in the KB :) Keif Gwinn IARNA, a Hostway Company scotts sufferance wharf 1 mill street. london. se1 united kingdom t/ +44 207 231 7766 f/ +44 207 231 2327 www.iarna.co.uk Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
